In the animal kingdom, the alpha male is the dominant member of the community. He’s like a cartoon caveman, commanding deference. The betas are wingmen, collaborative and conciliatory. In human terms, betas make the best mates. They do more in the house, and probably in the bedroom, because they know how to hasten the greater good. The beta has poetry in him, and a touch of youthful idealism. He’s sure of who he is, and not constantly trying to prove his value in materialistic terms. (Alpha: Your expensive car doesn’t make you interesting.) The beta can earn a lot of money, or a little, but the money’s not the thing; he profits because he works well with others.

There’s something rebellious about the beta male; he challenges the social order rather than succumbing to it. The beta male doesn’t buy in to the basest stereotypes about male behavior, and that’s hugely sexy.

That guy is so unassuming, affable and genuine. I wonder if he's a Beta Male...

The opposite of Alpha male. In modern society an Alpha male not only requires physical prowess, but also confidence and attitude. The Beta male of modern society usually, only has one of these traits, if any. The Beta male tends to be smart, quiet and unconfrontational. If lucky, beta males can get a hot chick once in her 30's, after she's tired of fucking the Alpha Males, and decides to settle down with a beta male for money and stability.

Alpha Males get everything, Beta Males get the left overs. It's a little thing called "Life"..

A man who is content with nontraditional gender roles; i.e., he is not threatened by intelligent and/or powerful women, and he does not have to be in control of every situation to maintain his sense of self. (Frequently, he does manifest a quiet kind of confidence and control over his surroundings, but it's not important to him that this is noticed by others.)

A beta male is often introverted, intelligent, and introspective. Though he may have been branded a "nerd" growing up, the adult beta is frequently a thoughtful, capable, and fascinating individual whom many women find appealing.

Alpha males, especially those of lesser intelligence and abilities, tend to feel threatened by beta males, who are increasingly preferred by women in modern times.

Peter Parker (Spider-Man) and Jim Halpert (The Office) are famous examples of beta males.

A bullshit subclass of men invented by so-called "alpha males" to classify anybody who's not spending 99.9% of their waking hours working out and practicing pick-up lines that they will later use on unsuspecting women. A beta male is someone who "sucks up to females" , known in the real-world as "RESPECTING women and their rights" and if in a couple are cock-blocking "better men" (read: I have abs and backnea ARGH!) .

In other words , "alpha" males are compensating for their lack of real personality by making up the notion that they are on top of men who are perfectly good people but are not paragons of male beauty.

A man who is obsessed with trying to convince everyone around him that he is an alpha male. Beta males are the most violent and aggressive of all men. Prisons are filled with beta males. A true alpha male never needs to convince anyone, doesn't care if he is one, and might not even know it. The genuine admiration and respect that a man receives from other men, due to his good character, intelligence, and leadership, is what makes an alpha male. Beta males will never attain alpha status by demeaning other men. Women who are attracted to beta males share the same poor character and low self esteem.

beta male: "do you want me to go beat up that creepy guy that keeps trying to talk to you?"
woman: "sure"

A beta male is a male who buys into the feminist lie that men should be subservient to women. He believes that being submissive to a woman, caring, and gentle, will result in her returning his affection. He believes that he must buy women things in order to garner their attention. He does not understand that women desire confidence and willpower in a man.

Pete was a beta male because he bought the girl he just met at the bar a drink, making his subservience to her clear. He won't be getting laid tonight.
